Vostok 2 - Mission Highlights

Mission Highlights

Gherman Titov launched from Gagarin's Start at Baikonur Cosmodrome on 6 August 1961 at 0600 UTC aboard the Vostok 2 spacecraft. Radio personality Yuri Levitan interrupted Radio Moscow programming with an announcement of the flight at 0745 UTC.

Nausea set in as Titov escaped Earth's gravity, which caused him to vomit when he tried to eat one of his planned meals. Soviet space program officials suspected disturbance of Titov's vestibular system was to blame, leading them to begin early investigations into what is now known as space adaptation syndrome, or space sickness. Titov is believed to be the first spacefarer to experience the condition.

Titov took manual control of the spacecraft's attitude for a time as he passed over Africa on his first orbit and would again at the end of the seventh orbit; the controls were reported to function well. Titov exchanged greetings with Soviet Premier Nikita Khrushchev as he passed over the Soviet Union at the end of his first orbit, replicating Gagarin's feat.

A camera aboard the spacecraft transmitted smiling pictures of Titov to the ground as he passed over Soviet territory on the fifth orbit. Titov settled down to sleep during the seventh orbit; he awoke over eight hours later, 37 minutes after the scheduled end of his sleep period. Sleep did not relieve Titov's serious discomfort; he still felt very ill after awaking. After 12 orbits Titov suddenly began to recover, and became "completely functional and fully fit".

Detailed information about the radio frequencies used by the spacecraft were made public before Titov's flight; listening posts around the world picked up voice and telemetry signals from Vostok 2, allaying suspicions that the spaceflight might have been faked.

As on Vostok 1, the Vostok 2 service module failed to detach from the reentry module when commanded and reentry began with the former still attached; the conjoined modules gyrated violently until aerodynamic heating burned through the straps still holding them together. Titov ejected from the capsule as planned and parachuted separately to land at 0718 UTC on 7 August 1961, near Krasny Kut, Saratov Oblast.

The Vostok 2 landing site coordinates are 50°51′10″N 47°01′14″E / 50.85276°N 47.02048°E / 50.85276; 47.02048, which is 11.5 km South of Krasny Kut, Saratovskaya oblast in the Russian Federation. At the roadside site are two monuments dedicated to the Vostok 2 mission. The larger one is a 9 meter tall, silver painted stone sculpture, that resembles a single bird's wing pointed skyward. The center of the wing has a series of looping openings, one atop the next, that resemble a row of feathers. To the right of the wing sculpture is a 2 meter high, silver painted square stone block, with a rounded corner on the front side. A portrait of Titov, wearing a space helmet, is on one side of the stone block, the other side contains red painted text commemorating the mission.

In 1964, the Vostok 2 spacecraft was reused as a ballast weight in a test of an experimental parachute system planned for the Voskhod spacecraft. The protoype malfunctioned, shattering Vostok 2 into tiny pieces.
